Assessing reliable and clinically significant change on Health of the Nation Outcome Scales: method for displaying longitudinal data

Abstract

Our study proposes a methodological framework for computing RCSC normative data on a widely used outcome scale and for identifying different degrees of clinical change.

Outcome of community-based rehabilitation program for people with mental illness who are considered difficult to treat

“…Similar assumptions were made for the SOFAS: the reliable change was a variation of 10 points, and we assumed 51 as the cutoff point to distinguish between serious (<51) and moderate (≥51) impairment in social/ occupational functioning [18].…”

“…We conducted a categorical analysis on the HoNOS total score modifications using the criteria for reliable and clinically significant change [18]. According to these criteria, a change on the HoNOS total score was reliably detected when it was ≥7 points.…”

Comparing the performance of English mental health providers in achieving patient outcomes

“…Parabiaghi et al (2005) applied a measure of Reliable and Clinically Significant Change (RCSC) to HoNOS data in order to compare outcomes. Reliable change (RC) was calculated as follows:…”

Effectiveness of hospitalisation in acute psychiatrie in-patient units in Lombardy (Italy)

“…Lo scopo di questo test e assicurarsi che il cambiamento osservato in un individuo: 1) sia al di la di quello che potrebbe essere attribuito aU'errore di misura o al caso (cambiamento riproducibile), e 2) porti il paziente da un livello di gravita clinico ad uno non clinico (significativo cambiamento clinico). In questa analisi abbiamo considerato migliorati in modo riproducibile e clinicamente significativo i pazienti che avevano una riduzione di almeno 7 punti HoNOS tra i punteggi totali della scala di ammissione e dimissione (cambiamento riproducibile) ed erano scesi al di sotto del cut-off'di 12, cut-off che separa la categoria dei pazienti gravi da quelli non gravi (Parabiaghi et al, 2005).…”
